Prithvi is primarily associated with which missile class?

Correct Answer: Option C — **Surface-to-surface ballistic missile**. **Surface-to-surface ballistic missile** is the accurate answer because Prithvi was developed as an Indian surface-to-surface ballistic missile series. This identifying fact establishes its correct connection with ballistic missile and distinguishes it from the other defence-related choices. Why the other options are incorrect: Option A — **Multirole fighter aircraft**: This is actually associated with combat aircraft; specifically, Rafale is a twin-engine multirole combat aircraft capable of air-to-air and air-to-ground missions. Option B — **Surya Kiran**: This is actually associated with army exercise; specifically, Surya Kiran is a recurring joint training exercise between the armies of India and Nepal. Option D — **New Delhi**: This is actually associated with headquarters; specifically, the Headquarters Integrated Defence Staff functions in the national capital as a tri-service organisation. Exam Takeaway: Link **Surface-to-surface ballistic missile** with its exact **ballistic missile** association for fast **Indian Defence GK** revision.
